WATER METERING

EXTERNAL ANTENNA

Pulse reader NB-IoT module with integrated battery and up to 4 digital inputs compatible with all pulse generators on the market.

Long range and secure communication via the NB-IoT network with remote monitoring of device operation and performance and long-term battery autonomy.

BASIC FEATURES

Broad communication

IP68 protection

Easy installation

Advanced communication with the NB-IoT module

The module uses the LTE Cat NB1/NB2 (NB-IoT) standard for wide coverage and reliable data transmission, even in areas with weak signal.
High RF sensitivity up to -129 dBm allows the device to operate effectively in demanding environments with low signal strength.
External antenna ensures a stable and strong connection, which enables continuous monitoring and remote control of the device.

The system automatically detects and immediately notifies users via the app in the event of a water leak, reducing potential damage and water loss.
Continuously monitors and informs users of any irregularities, such as backflow, magnet manipulation or cable problems, enabling timely intervention
Configuring data display according to specific user needs
Support for remote firmware updates (FOTA/OTA) ensures that the device always uses the latest software version, increasing security and functionality.

The device comes with an integrated Li-SOCl2 battery with a capacity of 19 Ah, which allows up to 10 years of operation in standard configuration.
The integrated battery can be easily replaced without the need to lose IP68 protection, thus ensuring continuity of operation and reducing maintenance costs
Built-in alarm warns of low battery level, allowing timely replacement and ensuring uninterrupted operation of the device
